Participants were asked to rate the answers to the following question regarding concerns and benefits of use non-peer-reviewed models, “If you had the need to use a still-non-peer-reviewed model or method, how would you rate the following concerns and benefits?”. Rating scale was from 1 (red) to 5 (dark green) stars. Histogram dimensions are represented as 100%, where 100% is the total number of participants of each subgroup: human-based (39), animal-based (30) and both (44) model users. The stacked chart, calibrated around the neutral score (3 stars), shows the number of respondents based on their degree of agreement and segmented by researchers’ use of animal- or human-based or both models.
